Since pulmonary nodules are its most common radiological feature, they can clinically and radiologically mimic lung cancer, TB, and other pulmonary mycoses. The sensitivity of cultures and the Cryptococcal (CrAg) antigen with lateral flow device on serum are rarely positive in the absence of disseminated disease. [20]
Cryptococcal antigen from cerebrospinal fluid is thought to be the best test for diagnosis of cryptococcal meningitis in terms of sensitivity, though it might be unreliable in HIV-positive patients. [12] The first genome sequence for a strain of C. neoformans (var. neoformans; now C. deneoformans) was published in 2005. [5]
CD58, lymphocyte-function antigen 3 (LFA-3), is a glycoprotein that plays a vital role in the body's immune response.The natural ligand to CD58, CD2, is most commonly found on the surfaces of both T cells and Natural Killer cells (T/NK cells). [3]
Cancer/testis (CT) antigens are a group of proteins united by their importance in development and in cancer immunotherapy. In general, expression of these proteins is restricted to male germ cells in the adult animal. However, in cancer these developmental antigens are often re-expressed and can serve as a locus of immune activation.
Tumor antigen is an antigenic substance produced in tumor cells, i.e., it triggers an immune response in the host. Tumor antigens are useful tumor markers in identifying tumor cells with diagnostic tests and are potential candidates for use in cancer therapy .
A new blood test was found to detect colon cancer with more than 80% accuracy — and to rule it out for 90% of healthy people. Doctors speak about how this could improve screening rates and outcomes.
Lymphocyte function-associated antigen 1 (LFA-1) is an integrin found on lymphocytes and other leukocytes. [1] LFA-1 plays a key role in emigration, which is the process by which leukocytes leave the bloodstream to enter the tissues. LFA-1 also mediates firm arrest of leukocytes. [2]
Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella , while Cryptococcus was reserved for the yeasts.
